Some go on to trade schools or get further training for jobs they are interested in. Some go into the arts, some are craftsmen, some take a little time out to travel, and some start their own businesses. But our graduates find and work at what they want to do.

But, if you observe children learning in their first few years of life, you can see that they can and do learn on their own - we leave them alone to crawl, walk, talk, and gain control over their bodies. It happens without much help from parents.
